Foams and Foam Materials Specifications

Material / Composition



	Your choices are...
	Plastic / Polymer		Materials are industrial plastics, elastomers, intermediates, monomers and other specialty polymers or compounds.
	Metal Foam		Materials consist of a metal or metal alloy.
	Ceramic Foam		Materials consist of a ceramic material.
	Elastomer / Rubber		Elastomers and rubber materials are characterized by their high degree of flexibility and elasticity (high reversible elongation). Elastomers and rubber materials can be based on a variety of systems such silicone, polyurethane, chloroprene, butyl, polybutadiene, neoprene, natural rubber or isoprene and other synthetic rubber or compounds.
	Thermoplastic		Thermoplastics can be repeatably softened by heat and then hardened, or set by cooling, which allows parts to be injection molded and scrap to be reprocessed.
	Thermoset / Crosslinked		Thermoset plastics and thermoset resins are crosslinked polymeric resins cured using heat or heat and pressure. Cured thermoset resins generally have higher resistance to heat compared to thermoplastics, but melting cannot reprocess them.

	Polymer / Chemical System:
	Your choices are...
	Latex Foam		Water-based resins, water borne resins or latex are water soluble or water emulsion based resin systems that typically do not contain any VOC solvents. Latex is a term often used for latex rubber products. Typically, water based resins will result in less environmental or regulatory control related problems. Latex or emulsions based products consist of resin or polymer droplets dispersed and suspended in a water carrier or solvent.
	Polyester		Thermosetting resins or plastics are based on the polyester (alkyd) system. These materials should not be confused with thermoplastic polyesters or PET resins. Also, foam using a polyester polyol as a component of the polymer chemical system.

	Special Features
	Your choices are...
	Chemical / Fuel Resistant		Material designed to be resistant to damage by acids, alkalis, general chemicals and oils. Material is resistant to damage by exposure to oil or fuel. These materials find applications in sealing fuel or oil tanks.

	Electrically Conductive		Foam material designed with relatively high electrically conductivity or low electrical resistivity for electronic, anti-static or electrostatic discharge (ESD) applications. Usually, a conductive filler is added into the foam to increase conductivity.
	Expanding		Expanding foam products are applied in the unexpanded form and then blowing agents or mechanisms within the material expand the foam. Expanding foam products are available in the film, sheet or sprayable forms.
	Felt / Permanent Set		Foam felt or felted foams have a permanent set. Compression set is the permanent height reduction caused by compression of the foam under specified conditions of load, temperature, and time.
	Flame Retardant		Material will reduce flame spread or resist ignition when exposed to high temperature or insulate the substrate and delay damage to the substrate. A UL 94 Rating indicates the material is flame retardant in accordance to Underwriters Laboratories, Inc. (UL) Flame Class 94V-0 or other equivalent ISO standards. Material will reduce flame spread or resist ignition when exposed to high temperatures, or insulate the substrate and delay damage to the substrate
	FOF (Foam Over Fabric / Screen)		FOF products consist of foam over fabric or screen. The fabric provides improved support. Integral screen provides EMI shielding capabilities.
	Integral Skin		Foams formed with an integral skin. A tougher, higher density skin layer is formed against the mold surface. While a lower density core is produced with blowing agents.
	Intumescent		Intumescent foams are combustion modified polymer foams. When a flame is applied, the surface of the foam chars, forming a protective shield between the flame and the foam underneath. The carbon char formed has a low thermal conductivity and high oxidation resistance.
	Hydrophilic / Absorbent		Foam material is hydrophilic, which means the surface can be wet by water. Sponges or water absorbent foams are hydrophilic. Hydrophobic foams will repel water.
	Hydrostatic Pressure Resistant		Foam is resistant collapse when exposed to hydrostatic pressures, which can occur in deep sea, composite structure molding or pultrusion applications.
	Thermal Insulation		Foam thermal insulation or thermal insulating foams provide a thermal barrier between components and a heat or cold source.
	UL Approved / Listed		The material is approved to or recognized and listed under the requirements of Underwriters Laboratories, Inc. (UL).
	Viscoelastic / Memory		Memory foams have a viscoelastic nature. Materials with a viscoelastic nature have a delayed response when a load is removed; i.e., they do not spring back quickly.
	Waterproof		Waterproof foams do not dissolve or degrade in strength when exposed to water. The foam may still absorb water if the product is hydrophilic and has open porosity.
	Weather / UV Resistant		Plastic or elastomer foams are resistant to ultraviolet (UV) light or sunlight. Some non-UV resistant foams will crack, yellow or degrade on exposure to UV light. Weather resistant materials are plastic or elastomer foams that can withstand exposure to the elements, such as wind, rain, snow dust, humidity, heat, cold and other weather conditions.

Mechanical & Physical Properties


	Bulk Density		Density is the mass per unit area for a material. Bulk or apparent density is dependent on the theoretical density (density 100% dense body) and the actual porosity retained after processing or packing of the pellets or powder.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Tensile Strength		Tensile strength at break is the maximum amount of stress required to fail or break the material under tension loading test conditions. Tensile tests are typically performed according to test procedure standards such as ASTM D-638 or ISO 527-1, ASTM D-1708, ASTM D-2289 (plastics at high strain rates), and ASTM D-882 (thin plastic sheets) as well as other OEM proprietary standards.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Tensile Modulus (E)		Tensile modulus, Young's modulus, or the modulus of elasticity (E) is a material constant that indicates the variation in strain produced under an applied tensile load. Materials with a higher modulus of elasticity have higher stiffness or rigidity.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Elongation		Elongation is the percent amount of deformation occurring during a tensile test or other mechanical test.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Tear Strength		Tear strength is used to measure the tear resistance of foam rubber, elastomeric foam or other thin, flexible foam materials. A notched specimen of known thickness is ripped apart by an applied load. The applied load required to tear divided by the material thickness provides the tear strength in force per unit length (e.g., pounds per inch, pli).
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Noise Reduction Coefficient (NRC)		Noise reduction coefficient (NRC) is a rating given to an acoustical material directly related to the material's ability to absorb noise, according to ASTM D423. NRC is determined by averaging the measured sound absorption coefficients across a series of frequencies between 250 to 2,000 Hz. NRC gives an indication of the level of noise attenuation a material can provide over a range of frequencies.
